Beispiele

Zeigt, wie eine Gruppe von Formen erstellt und deren Inhalt mithilfe eines Dokumentbesuchers gedruckt wird.

public void GroupOfShapes()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Wenn Sie „nicht-primitive“ Formen erstellen müssen, z. B. SingleCornerSnipped, TopCornersSnipped, DiagonalCornersSnipped,
    // TopCornersOneRoundedOneSnipped, SingleCornerRounded, TopCornersRounded, DiagonalCornersRounded
    // Bitte verwenden Sie DocumentBuilder.InsertShape-Methoden.
    Shape balloon = new Shape(doc, ShapeType.Balloon)
    {
        Width = 200, 
        Height = 200,
        Stroke = { Color = Color.Red }
    };

    Shape cube = new Shape(doc, ShapeType.Cube)
    {
        Width = 100, 
        Height = 100,
        Stroke = { Color = Color.Blue }
    };

    GroupShape group = new GroupShape(doc);
    group.AppendChild(balloon);
    group.AppendChild(cube);

    Assert.True(group.IsGroup);
